Abstract
A system for detecting an incontinence event includes a pad which is deployable on a mattress and which, as deployed, has an open circuit comprised of a first conductor extending from a first terminal of an RFID inlay, and a second conductor extending from a second terminal of the RFID inlay. The system also includes an RFID reader subsystem having an array of two or more spatially distributed antennas. The detection system commands spatially and temporally varying transmission of energy from the antenna array at a variety of powers and frequency settings. The detection system monitors the antenna array for a return signal resulting from the transmission. The return signal has a moisture status indicator which indicates whether or not liquid is present on the pad. The detection system also causes communication of a WET or DRY status to a destination. The reported WET or DRY status depends on the moisture status indicator.
